The story is over. The guy behind the Youtube video of Hyper-V crashing and claiming it was unstable finally admitted he was wrong and removed the video. It turns out that the VMware lab didn’t meet the minimum requirements for running Windows Server 2008. When MS did bring their lab down to these configurations they were able to reproduce a crash of a VM. After some digging they found a year old publicly available patch fixed the situation.
The lesson here is, don’t believe the FUD that VMware marketing is putting out there, e.g. “Hyper-V = ESXi”. Yes, MS marketing creates plenty of lame ducks too but I’ve never seen them do anything like VMware.
